The Norwood scale divides male pattern baldness into seven stages, from a barely receded hairline to loss of the entire top of the scalp with a horseshoe of hair remaining at the back and sides.
It is not academic. Your stage determines whether medication alone is realistic, whether surgery makes sense yet, and roughly how many grafts you would need.
Most men can place themselves within a stage or two using a mirror and a phone camera. Here is how the scale works and what each stage actually implies.
The seven stages
| Stage | What it looks like | Usual approach |
|---|---|---|
| I | No meaningful recession. An adolescent hairline maturing | Nothing needed |
| II | Slight recession at the temples, forming a shallow M | Monitor; medication if progressing fast |
| III | Deeper temple recession. The first stage considered clinical baldness | Medication; surgery possible depending on age |
| III vertex | Stage III hairline plus thinning at the crown | Medication, often with surgery |
| IV | Clear crown loss with a band of hair separating it from the front | Surgery usually appropriate |
| V | The separating band narrows and thins | Surgery, staged if needed |
| VI | The band disappears; front and crown merge | Surgery with realistic density expectations |
| VII | Only the horseshoe at back and sides remains | Limited — depends entirely on donor supply |
Why the stage changes the plan
Two things scale with severity: how many grafts the area needs, and how much donor hair you have to spare.
At stage III, a modest number of grafts can restore the front convincingly. At stage VI, the area needing coverage has grown while the donor area has stayed the same size. The arithmetic stops working somewhere around stage VI or VII, which is why realistic density expectations matter more the later you leave it.
Can you predict how far it will go?
Not precisely, but three signals help.
Family history is the best available predictor. Look at your father, brothers and grandfathers on both sides — the old idea that baldness comes only from your mother’s side is not accurate.
Age of onset matters. Loss starting in the early twenties tends to progress further than loss starting in the late thirties.
Rate of change is the most useful of the three. Photograph the same angles in the same light every three months. Comparing images across a year tells you far more than any single assessment.
Why women use a different scale
Norwood does not apply to female hair loss, which follows an entirely different pattern — the frontal hairline is usually preserved while the parting widens. A separate three-grade scale (Ludwig) is used instead. See our guide to hair transplants for women.

At HairX Clinics we examine the scalp under magnification to see whether follicles are miniaturising or already gone, then tell you honestly whether medication alone would serve you better than surgery.
Frequently asked questions
Can you move backwards down the scale?
Not naturally. Medication can thicken miniaturising hair enough that the visible stage appears to improve, and surgery redistributes hair, but the underlying genetic process does not reverse.
How fast do people move between stages?
Enormously variable. Some men sit at stage III for decades; others move from II to V within a few years. Rate of change in your own photographs is the only reliable guide.
Is a maturing hairline the same as balding?
No. Most men’s hairlines rise slightly in their late teens and early twenties as the adolescent hairline matures. That is normal and stops. Continued recession beyond that is different.
What stage is too advanced for surgery?
There is no fixed cut-off — it depends on donor supply, not stage number. Someone at stage VI with dense donor hair may be a better candidate than someone at stage IV with a thin donor area.
Should I start treatment at stage II?
Possibly, if it is progressing quickly or your family history suggests extensive loss. Protecting a miniaturising follicle is far easier than replacing one that has gone. Discuss it with a doctor — see our review of treatments.
When should you get a hair transplant?
The right time to get a hair transplant is once the pattern of loss has stabilised enough to predict where it is heading, which for most men means Norwood stage III or later with a documented rate of change over at least a year. Operating earlier risks building a hairline in front of hair that later recedes behind it, leaving an isolated strip that needs a second procedure to correct. Photographing your hairline every three months is the cheapest way to establish that rate before you commit.
What age should you get a hair transplant?
Most surgeons prefer a patient to be at least twenty-five before a first hair transplant, because loss before that age is often still accelerating and its final extent cannot be judged. Age is not really the criterion — the stability of the loss and the density of the donor area are — but the two correlate closely enough that younger patients are usually advised to start on medical treatment and reassess rather than operate.
Work out your stage, photograph it, and check again in three months. That single habit tells you more about what you need than any consultation can on its own.

HairX is the first hair transplant clinic in the world to show you the twelve-month result and the graft count you need before you speak to anyone. It is free and it takes minutes. The report covers your stage of hair loss, what your donor area can realistically give, and how the result comes in month by month, including the third month, when it looks worse before it gets better.
